Overview

The ARRMA CVD Axle 8x44.5mm (2) Z-AR310590 is an essential spare part for RC enthusiasts running ARRMA's high-performance Kraton, Notorious, Outcast and other brushless speed trucks. Whether you're a competitive racer, weekend basher, or someone new to the world of RC cars UK, having quality replacement axles on hand is crucial for keeping your RC vehicle in peak condition. These CVD axles are precision-engineered direct replacements that restore your truck's drivetrain to factory specifications, ensuring smooth power delivery and reliable performance on any terrain.

Constant Velocity (CVD) axles are a fundamental component of modern four-wheel-drive RC vehicles, transmitting engine power to the wheels whilst allowing for suspension articulation and steering movement. The ARRMA CVD Axle 310590 is manufactured to the exacting standards ARRMA is known for, utilising super-tough steel construction that withstands the demands of high-speed racing and aggressive bashing. This pack includes two axles, allowing you to replace both front or rear axles in one convenient purchase, making it an excellent value option for RC model enthusiasts who want to maintain their equipment properly.

ARRMA's Kraton, Notorious and Outcast lines are among the most popular brushless RC speed trucks available in the UK market, and these CVD axles are manufactured specifically to fit these models perfectly. The 8x44.5mm dimensions ensure precise fitment and optimal performance across multiple model variants and generations, from the 1/8 Kraton 6S through to the newer EXB and AVC variants. By choosing genuine ARRMA spare parts like these CVD axles, you're investing in reliability and longevity for your RC machine.

Key Features

• Super-tough steel construction — The axles are forged from high-quality steel material engineered to handle the immense rotational forces and shocks that come with high-performance RC driving, whether you're running on dirt tracks, rocky terrain, or concrete surfaces.
• Precision-manufactured tolerances — Each CVD axle is manufactured to exacting specifications, ensuring perfect fitment into your ARRMA transmission and delivering the smooth, friction-free operation that keeps your truck running efficiently without binding or grinding.
• Hard-wearing durability — The robust steel construction resists wear and deformation even under extreme conditions, meaning these axles will provide reliable service across hundreds of runs and maintain consistent performance throughout their service life.
• Consistent performance on all terrains — Whether you're bashing on grass, concrete, dirt tracks, or rocky terrain, these CVD axles deliver the same reliable power transmission in every condition, making them suitable for both racing and recreational use.
• Friction-free operation — Precision manufacturing ensures minimal friction losses in the drivetrain, maximising power transfer from your brushless motor to the wheels and improving overall acceleration and efficiency.
• Pack of two axles — The inclusion of two CVD axles in each pack means you can replace both front or both rear axles in one go, reducing downtime and ensuring matched wear characteristics across your suspension.

Technical Performance

The ARRMA CVD Axle 8x44.5mm represents years of development in drivetrain engineering for high-performance RC trucks. Measuring 8mm in diameter with a 44.5mm length, these axles are engineered to fit perfectly within ARRMA's transmission housings whilst delivering the precise dimensional tolerances that allow smooth rotation without play or wobble. The super-tough steel material selection is critical for vehicles powered by brushless motors, which deliver consistent, high-output power to the drivetrain. Unlike brushed motors that naturally have power delivery variations, brushless systems on RC cars like the Kraton 6S place constant, unrelenting stress on drivetrain components, making material quality and precision engineering essential. The CVD design allows for angular articulation whilst maintaining constant velocity power transmission, which is absolutely vital during cornering and suspension compression on uneven terrain. When running high-performance setups with brushless electronics, properly functioning CVD axles are essential for translating motor power into wheel rotation without losses. The precision manufacturing process ensures that each axle operates within the tightest tolerances, eliminating the friction that would otherwise reduce efficiency and heat the drivetrain unnecessarily. For RC enthusiasts running their vehicles hard on tracks and terrain across the UK, these replacement CVD axles maintain the performance envelope that ARRMA designed into their speed trucks, ensuring your machine continues to deliver the handling characteristics and acceleration you expect.

What's in the Box

• 2 x CVD Axle - 8x44.5mm

Compatibility

The ARRMA CVD Axle 8x44.5mm (2) is specified as a standard part for the following models: ARRMA 1/8 Kraton 6S 4x4 (all variants including EXB and AVC versions), ARRMA 1/8 Notorious 6S 4x4 (multiple versions), ARRMA 1/8 Outcast 6S 4x4 (including EXB AVC variants), ARRMA 1/7 Big Rock 6S 4x4, and ARRMA 1/7 Fireteam 6S 4x4.

Frequently Asked Questions

• What is a CVD axle and why does my RC truck need one? — A CVD (Constant Velocity) axle is a drivetrain component that transmits power from your motor to the wheels whilst allowing for suspension movement and steering angles. CVD axles are essential on four-wheel-drive RC trucks because they maintain consistent power delivery even when the suspension is compressed or the wheels are turned at angles, ensuring smooth acceleration and reliable handling across all terrain types.
• How often should I replace my CVD axles? — CVD axles typically last for many runs under normal usage, but they can be damaged through impacts, extreme loads, or general wear from high-performance driving. Having spare axles on hand ensures you can keep your RC truck running without long delays if one breaks. The lifespan depends heavily on driving style and terrain; aggressive bashers should stock spares more frequently than casual racers.
• Are these axles compatible with all Kraton models? — These CVD axles are compatible with multiple versions of the ARRMA Kraton 6S 4x4, including the standard RTR model, Roller versions, and the newer EXB and EXB AVC variants. However, compatibility can vary across different Kraton generations and scales, so always verify your specific model number before ordering.
• What makes ARRMA CVD axles better than aftermarket alternatives? — ARRMA genuine CVD axles are precision-engineered to exact specifications using quality materials selected for durability and performance. They provide perfect fitment, consistent operation, and are designed and tested specifically for ARRMA vehicles, ensuring reliability and warranty support that aftermarket parts may not offer.
• Can I use these axles for racing or just bashing? — These CVD axles are suitable for both racing and recreational bashing. The super-tough steel construction and precision manufacturing make them suitable for the demands of competitive racing applications, whilst their durability also makes them ideal for weekend bashers who push their trucks hard on varied terrain.
• How do I know if my CVD axle needs replacing? — Signs of CVD axle wear or damage include clunking noises from the drivetrain, vibration during acceleration, difficulty steering, or visible bending or cracks in the axle itself. If you've had a significant impact or your truck doesn't feel as responsive as usual, it's worth inspecting your axles and replacing them if damaged.
